28c386422b state when the predicates are true 
"returns" is not used in this way in logic programming. "return"
suggests that something went away and is now coming back, but this is
never the case in these situations. The arguments may be variables or
also fully known at the time of the call in most cases.

46dfaa5b28 ENHANCED: library(files): Error handling if requested files do not exist. 
We now throw exceptions instead of failing silently, or even crashing
when using file_size/2 etc. with nonexistent files.

2768beec4c ADDED: path_segments/2 for portable reasoning about path components. 
The platform-specific directory separator is taken into account.
The clean representation of segments as a list simplifies reasoning.

17dd9239b6 ADDED: file_creation_time/2 and file_access_time/2. 
The code can be simplified once if- and while-let-chains are available:
